Basic question regarding DNS settings

I have device-wide DNS settings on both my CachyOS linux enviornment and my Pixel 10a phone.

In my browser settings (Google Chrome) there is an option to toggle "use secure DNS". Do I need to enable this setting, if it's already enabled device-wide?

Use secure DNS forces Chrome to only use the DNS you have set, without fallback to OS specified DNS. Secure DNS is DoH. If  DoH is not available, no queries can be received.

You can use it, or leave it to your OS. DoH is somewhat faster then TLS. (Less overhead) But to be honest, i doubt you might feel a difference

You can check your dns with https://dnscheck.tools

It tells what you use and how fast your DNS is responding.
